(first embodiment)
Fig. 1 is the profile perspective of gas permeable member of the present invention.Fig. 2 is the perspective view of the gas permeable member of Fig. 1.Fig. 3 is the cutaway view that expression is installed to first and second gas permeable members state on the framework of the equipment that need take a breath.As shown in Figure 3, be mounted in the portion 53, can stop the allotrylic ventilations of carrying out simultaneously in the framework 51 such as water droplet by the nozzle-like filter on the framework 51 that gas permeable member 100 is installed to the equipment of being arranged on.In addition, can keep the pressure in the framework 51 to equate with external pressure.
As Fig. 1, Fig. 2 and shown in Figure 3, gas permeable member 100 has cartridge 11, breathable filter 19 and cover 31.Wherein, in Fig. 1, omitted breathable filter 19.The roughly cylindrical shape of cartridge 11 forms the ventilative path A R that directly is connected with the framework 51 of equipment by the space in the tube
1 Breathable filter 19 is installed to a peristome 15 of cartridge 11.Cover 31 is that the parts of the cartridge 11 of breathable filter 19 from the embedding of breathable filter 19 1 sides have been installed.As shown in figures 1 and 3, in the cartridge 11 openings at two ends portions, as by the aperture area S2 of the filter side opening portion 15 of the peristome of breathable filter 19 obturations greater than as and the filter of framework 51 be mounted the aperture area S1 of the connection side opening portion 13 of the peristome that portion 53 is connected.Thus, can enlarge the effective area of breathable filter 19 to greatest extent, improve the Air permenbility of unit interval.
The effective area of breathable filter is meant that reality is to the area of the inside and outside ventilative contributive part of cartridge 11 in the breathable filter 19.In addition, when will the direction vertical with the thickness direction of breathable filter 19 being defined as in the face aspect WL, the aperture area of cartridge 11 is represented with the aperture area relevant with direction WL in this face.Wait as can be seen from Fig. 1, the parallel direction of the thickness direction of breathable filter 19 and the central axis O of cartridge 11 is consistent.The direction parallel with central axis O is also referred to as axis direction.In addition,, the side at filter side opening portion 15 places is made as front side (below being) in Fig. 3, a side that connects side opening portion 13 places is made as rear side (above being) in Fig. 3 about the direction parallel with central axis O.
Below, each parts are elaborated, the structure to the gas permeable member under the state of assembling each parts 100 describes simultaneously.
As Fig. 1 and shown in Figure 3, cartridge 11 by as the connection side opening portion 13 of the peristome that is connected with the equipment of taking a breath, as the filter side opening portion 15 of the peristome of installation breathable filter 19 with will be connected side opening portion 13 and constitute with the main part 17 that filter side opening portion 15 is connected.The inside of main part 17 forms and connects the through hole that connects side opening portion 13 and filter side opening portion 15, and this through hole constitutes ventilative path A R
1On the interior circumferential portion that connects side opening portion 13, give taper TP, be mounted portion 53 with the filter of easy insertion nozzle-like.Filter side opening portion 15 be that the opening diameter at center is bigger than connecting side opening portion 13 with central axis O, it is thin that the wall ratio of radial direction connects side opening portion 13.
In addition, the opening diameter that connects side opening portion 13 represent taper TP inner periphery, be the opening diameter that filter is mounted the position that portion 53 and contacting of cartridge 11 begin.This is because taper TP considers that the installation easiness that the nozzle-like filter is mounted portion 53 is provided with, and connects the opening diameter of side opening portion 13 and should be substantially discusses being mounted being connected of portion 53 contributive position with filter.
As shown in Figure 5 and Figure 6, the main part 17 of cartridge 11 is made of the outside main body portion 173 of inner side main body portion 171 and this inner side main body portion 171 of encirclement.Inner side main body portion 171 and outside main body portion 173 are the concentric shape configuration of total central axis O.Wherein, outside main body portion 173 has the side shape of stretching out slightly forwards than inner side main body portion 171.That is, the front side end of outside main body portion 173 constitutes filter side opening portion 15.The result who satisfies such configuration relation is that the inwall of the main part 17 of cartridge 11 is stepped.Main part 17 with stairstepping at the assigned position of the directional correlation parallel with central axis O, produces phase change in the aperture area of direction WL in the face.That is, according to the stairstepping of main part 17, can obtain the opening surface product moment Δ S that connects side opening portion 13 and filter side opening portion 15 (=S2-S1).
In addition, cartridge 11 comprises a plurality of linking parts 43 that connect inner side main body portion 171 and outside main body portion 173.Linking part 43 is to form the part of one between inner side main body portion 171 and outside main body portion 173 and with both.In the present embodiment, with equal angles linking part 43 is set at interval at a plurality of positions of circumferencial direction.Therefore, 43,43 of adjacent linking parts form space SH.Space SH forwards side open and with the ventilative path A R of cartridge 11 inside
1Be communicated with.On the other hand, inner side main body portion 171 and outside main body portion 173 whole connection on the side circumferencial direction in the wings.Connect the internal diameter of the opening diameter of side opening portion 13 corresponding to inner side main body portion 171.
In addition, in the present embodiment, adopt the material of thermoplastic elastomer (TPE) as cartridge 11.Can be used as the kind of the thermoplastic elastomer (TPE) that the material of cartridge 11 uses, can the illustration polystyrene type, TPO, polyvinyl chloride, polyesters, polyurethanes, polyamide-based or fluorine analog thermoplastic elastomer.These thermoplastic elastomer (TPE)s all have good hear resistance, against weather and chemical proofing, and are therefore preferred.
In addition, the thermoplastic elastomer (TPE) that constitutes cartridge 11 preferably the compression set under 70 ℃ of following 22 hours (JISK 6301) conditions be that the hardness of (preferred below 50%) 70% below and A shape spring hardness tester mensuration is (preferred below 80) below 100.When compression set is excessive, because vibration and variations in temperature and be mounted between portion 53 (with reference to Fig. 3) and the cartridge 11 at the filter of equipment and be easy to generate the gap.In addition, when hardness is excessive, is difficult to that cartridge 11 is installed to filter and is mounted in the portion 53.In addition, in the present embodiment, the wall thickness that connects side opening portion 13 is adjusted into more than or equal to the wall thickness of inner side main body portion 171 and the wall thickness sum of outside main body portion 173, therefore when insertion nozzle-like filter as shown in Figure 3 was mounted portion 53, tightening force acted on filter and is mounted portion 53 fully.Therefore, gas permeable member 100 can easily not be mounted portion 53 from filter and comes off.
Then, the breathable filter of fixing in the filter side opening portion 15 of cartridge 11 19 can be made of the material that has dust tightness, water proofing property and gas permeability concurrently.So long as prevent the degree that water droplet is invaded, can use the fabric, nonwoven, net, the powder sintered porous body more than the 10 μ m of aperture or the foaming body that constitute by fibrous material as breathable filter 19.In addition, these materials can multiplely be used in combination, also the material that can use multiple stratification to form.When the surface is hydrophily, can apply with water and oil repellent agents such as fluorine class or silicones.
Need under the situation of high water proofing property, can use can be by the resin perforated membrane of manufacturings such as known pulling method, extraction method.The aperture of such perforated membrane can be set at below the 10 μ m.As required, can apply above-mentioned water and oil repellent agent.Consider that from the viewpoint of expecting abundant water proofing property the average pore size of perforated membrane is preferably more than the 0.01 μ m, below the 10 μ m.In the present embodiment, the perforated membrane that is made of polytetrafluoroethylene (PTFE) uses as breathable filter 19.In addition, in the present embodiment breathable filter 19 hot melts are applied to the filter side opening portion 15 of cartridge 11, but also can fix by using other methods such as adhesive.In addition, can breathable filter 19 be fixed on the cartridge 11 yet, but be installed on the cover 31.
Fig. 7 is the perspective view from the cover of the unilateral observation that embeds cartridge.Fig. 8 is the perspective view from the cover of the unilateral observation opposite with Fig. 7.As shown in Figure 7 and Figure 8, cover 31 is made of the side wall portion 39 of roughly rounded bottom 35 and tubular, and integral body has and is fit to prevent that water droplet etc. directly is attached to the cup-shaped form on the breathable filter 19.On the bottom 35 of cover 31, at the pad 33 that disposes overshooting shape in the face of a side of breathable filter 19.Pad 33 disposes with certain angle intervals in a plurality of positions (3 more than the position) of the circumferencial direction of rounded bottom 35.As shown in figures 1 and 3, under the installment state of cartridge 11 insert cover parts 31, pad 33 supports cartridge 11 along filter side opening portion 15, stops breathable filter 19 to be close on the bottom 35 of cover 31.Its result forms as ventilative path A R
2The gap of working.
In addition, on the side wall portion 39 of cover 31, be provided for fixedly a plurality of (more than 3) stator 37 of cartridge 11 in the position corresponding with the pad 33 of bottom 35.Stator 37 along the inner peripheral surface of side wall portion 39 rearward, be that the direction of cover 31 openings is extended.On stator 37, be provided for the taper TS that cartridge 11 is easy to slip into cover 31.The inward flange of stator 37 is compared with the inward flange of pad 33 and is positioned at the radial direction outside, therefore cartridge 11 is pressed in the cover 31, and cartridge 11 is advanced up to contacting with pad 33.As shown in Figure 3, under the installment state of cartridge 11 insert cover parts 31, the side wall portion 39 of cover 31 along the circumferential direction surrounds cartridge 11.On the direction parallel with central axis O, the stator 37 of cover 31 is fixing with cartridge 11 in the broad range that comprises filter side opening portion 15 and main part 17.Because the performance of the tightening force that inner side main body portion 171 and outside main body portion 173 all produce the strain by cartridge 11 has contribution, so cover 31 is firm with the assembling of cartridge 11.
Certainly, also can form cover 31, with the resin formation cartridge 11 of hard with elastomer.Also can form stator in cartridge 11 1 sides.But as shown in Figure 3, the filter that is arranged on as the nozzle-like on the framework 51 of ventilation object is mounted portion 53, is made by the resin or the metal of hard.Therefore, if form cartridge 11, then can provide to be installed to such filter simply and to be mounted gas permeable member 100 in the portion 53 with elastomer.
Then, when being mounted in the portion 53 to the filter that gas permeable member 100 is installed to the framework 51 of equipment, gas permeable member 100 roles describe.Consider that now the interior pressure of framework 51 is higher than the situation of external pressure.Gas (air) in the framework 51 is invaded the ventilative path A R of cartridge 11 by connecting side opening portion 13
1Gas also expands to the front end face 171a of inside subject portion 171 and the gap between the breathable filter 19.Gas by (seeing through) breathable filter 19 arrives the ventilative path A R between the bottom 35 of breathable filter 19 and cover 31
2Arrive ventilative path A R
2Gas, via the ventilative path A R that between adjacent stator 37 and 37, forms
3, be diffused into the outside of gas permeable member 100.
In addition, adopt the gas permeable member 101 of cartridge 12 as shown in Figure 4 also to be fit to.Gas permeable member 101 has and the identical cover 31 of explanation in Fig. 1 etc.Difference is the internal structure of cartridge 12.
Cartridge 12 shown in Figure 4 is identical with the cartridge 11 that illustrates previously greater than the aperture area this point that connects side opening portion 14 at the aperture area that makes filter side opening portion 16.Particularly, cartridge 12 is in the section that comprises central axis O (section of Fig. 4), and the inner peripheral surface 18p that connects the main part 18 between side opening portion 14 and the filter side opening portion 16 is the taper surface with respect to central axis O inclination certain angle.Thus, main part 18 becomes the shape towards filter side opening portion 16 1 sides (front side) enlarged-diameter.Like this, become taper, can make openings at two ends diameter (aperture area) difference by making inner peripheral surface 18p.Although such cartridge 12 cartridge 11 as the aforementioned not aspect the cool time when injection moulding because shape is fairly simple, therefore has advantages such as the metal die expense is low.
